FEATURES
VCC Current (Commercial/Industrial) — Operating: 55 mA — CMOS Standby: 3 µA Access Times —80/100 (Commercial or Industrial) —90/120 (Military) Single 5 Volts ±10% Power Supply Easy Memory Expansion Using CE1, CE2 and OE Inputs P4C164LL VERY LOW POWER 8Kx8 STATIC CMOS RAM Common Data I/O Three-State Outputs Fully TTL Compatible Inputs and Outputs Advanced CMOS Technology Automatic Power Down Packages —28-Pin 300 and 600 mil DIP —28-Pin 330 mil SOP DESCRIPTION
Inputs are fully TTL-compatible. Access times of 80 and 100 ns are available for commercial and industrial temperatures; access times of 90 and 100 ns are available for military temperature. CMOS is utilized to reduce power consumption to a low level. The P4C164LL device provides asynchronous operation with matching access and cycle times. Memory locations are specified on address pins A0 to A12. Reading is accomplished by device selection (CE1 LOW, CE2 HIGH ) and output enabling (OE) while write enable (WE) remains HIGH. By presenting the address under these conditions, the data in the addressed memory location is presented on the data input/output pins.
